Jump start and speed cycle your marine aquarium with our pre-seeded bio spheres. Each item is matured in one of our long-standing cryptic raceways containing a diverse blend of natural live rock for a minimum of two months to supply you with an excellent base of various bacteria for nitrification and denitrification. As an added benefit, these will contain beneficial microfauna. Nano-Tech BioSpheres are a durable dense arrangement of smaller spheres creating an ultra-high surface area. Each Sphere has a surface area of 580 square feet and can stabilize 17 gallons. 10 Spheres is roughly equivalent to 20+ pounds of Live Rock. This is a must with today’s man made and base rock that are primarily used to start reef aquariums. Wild Reef Pre-Seeded Bio Media must be put in aquarium water upon arrival to maintain its live benefits.
***BioSpheres are sold in packs of 3, 6, and 12***
